WebAug 8, 2024 · The following steps provide a guide for how to do this: 1. Compute the alpha value. Find the alpha value before calculating the critical probability using the formula alpha value (α) = 1 - (the confidence level / 100). The confidence level represents the probability of a statistical parameter also being true for the population you measure. WebIf your p-value is lower than your desired level of significance, then your results are significant. Using the z-table , the z-score for our game app (1.81) converts to a p-value of 0.9649. This is better than our desired level of 5% (0.05) (because 1−0.9649 = 0.0351, or 3.5%), so we can say that this result is significant.

When performing a t-test, we compare sample means by calculating a t-value (also called a t-statistic): t = ¯x −μ s/√n t = x ¯ − μ s / n. where ¯x x ¯ is the sample mean (i.e., the mean of the dependent variable’s measured values), μ μ is the population mean, s is the standard deviation of the sample, and n is the ... WebYour significance level should balance the desire to be confident in your results with the practical effect of the decision you plan to make. 3. Source a sample and gather data.
